CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority under 35 U.S.C. § 119(a) to Korean Application Serial No. 10-2014-0116101, which was filed in the Korean Intellectual Property Office on Sep. 2, 2014, the entire content of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a method of processing an image in an electronic device and an electronic device for the same.

BACKGROUND

Recently, with the development of digital technologies, various electronic devices including mobile communication terminals, Personal Digital Assistants (PDAs), electronic organizers, smart phones, tablet Personal Computers (PCs), and the like, which can perform communication and personal information processing while being carried, have come to market. Prices of the electronic devices vary, and capabilities of the devices also vary according to price. The electronic device may have various resolutions based on its capabilities

Meanwhile, a content provider (a content-providing device or a content-providing server) may provide an image file, which can be applied to a background image of the electronic device, a home screen image, a lock screen, or an icon of the home screen image, or an image installation file including a plurality of successive images to give an animation effect. However, as described above, the electronic devices have different resolutions, so the content provider should prepare various image files suitable for the respective resolutions of the electronic devices.

For example, the content provider may generate installation files, which simulate a user's mood such as a theme installation file mainly based on an image file, divide the files according to various categories, and provide the files. The user may access a server of the content provider by using the electronic device, download a desired installation file, and apply the downloaded installation file to a background image of the electronic device.

The content provider may provide one image file in various resolutions. That is, when one image file includes an image resource supporting all resolutions, the size of the image file becomes very large. In this case, the electronic device downloads not only the image resource at the resolution which can be applied to the electronic device, but also the image resource which is not suitable for the resolution of the electronic device. That is, the electronic device downloads unnecessary files and thus incurs the large data license fee.

In other cases, the content provider may configure image files divided according to each resolution, but in this case the content provider takes on the large costs of managing the image files. Alternatively, when the content provider provides an image file of one resolution, a high resolution electronic device may download an image file of inferior image quality.

SUMMARY

In accordance with an aspect of the present disclosure, an electronic device is provided. The electronic device includes: a communication interface configured to receive an image resource file from a content-providing server; a processor configured to read a shared image from the image resource file, identifying display information of the electronic device, determining an auxiliary image using a difference between the display information and the shared information, and generating a particular image based on the shared image and the auxiliary image and a display configured to display the generated particular image.

In accordance with another aspect of the present disclosure, an operation method of an electronic device is provided. The operation method includes: acquiring a shared image from an image resource file; acquiring an auxiliary image including using a difference between the image resource file and the shared image; and generating a particular image based on the shared image and the auxiliary image.

In accordance with another aspect of the present disclosure, an electronic device includes a computer-readable storage medium recording a program for executing a process. The process includes: acquiring a shared image from an image resource file; acquiring an auxiliary image including using a difference between the image resource file and the shared image; and generating a particular image based on the shared image and the auxiliary image.

FIG. 1 illustrates a network environment 100 including an electronic device 101 according to various embodiments of the present disclosure. Referring to FIG. 1, the electronic device 101 may include a bus 110, a processor 120, a memory 130, an input/output interface 140, a display 150, and a communication interface 160.

The bus 110 may be a circuit interconnecting the aforementioned components and transmitting communication (e.g., a control message) between the aforementioned components.

The processor 120, for example, may receive instructions from the aforementioned components (e.g., the memory 130, the input/output interface 140, the display 150, and the communication interface 160) other than the processor 120 through the bus 110, decode the received instructions, and perform operations or data processing according to the decoded instructions.

The processor 120 may perform predetermined functions of the electronic device 101. The processor 120 includes at least one Application Processor (AP) (not shown) and a Micro Controller Unit (MCU) (not shown). The AP and the MCU may be included in different Integrated Circuits (IC) packages, respectively. According to an embodiment, the AP and the MCU may be included in a single IC package.

The AP can execute an operating system (OS) or an application program to control a plurality of hardware and/or software elements connected to the AP and perform processing and calculation of various data including the multimedia data. The AP may be implemented by, for example, a System on Chip (SoC). According to an embodiment, the processor 210 may further include a Graphic Processing Unit (GPU) (not illustrated). The memory 130 may store instructions or data received from or generated by the processor 120 or other components (e.g., the input/output interface 140, the display 150, and the communication interface 160). The memory 130 may include programming modules, for example, a kernel 131, middleware 132, an application programming interface (API) 133, and applications 134. Each of the programming modules as described above may be formed by software, firmware, hardware, or a combination of two or more thereof.

The kernel 131 may control or manage system resources (e.g., the bus 110, the processor 120, and the memory 130) used to execute operations or functions implemented in the remaining other programming modules, for example, the middleware 132, the API 133, and the applications 134. Further, the kernel 131 may provide an interface that allows the middleware 132, the API 133, or the applications 134 to access and control or manage individual components of the electronic device 101.

The middleware 132 may serve to mediate between the API 133 or the applications 134 and the kernel 131, that is, allow the API 133 or the applications 134 to communicate and exchange data with the kernel 131. Further, the middleware 132 may perform control (e.g., scheduling or load balancing) for task requests received from the applications 134 by using, for example, a method of assigning a priority for use of the system resource (e.g., the bus 110, the processor 120, or the memory 130) of the electronic device 101 to at least one of the applications 134.

The API 133 is an interface (not shown) for allowing the applications 134 to control functions provided by the kernel 131 and the middleware 132, and may include at least one interface or function (e.g., instruction) for, for example, file control, window control, image processing, or text control.

According to various embodiments, the applications 134 may include a Short Message Service (SMS)/Multimedia Message Service (MMS) application, an e-mail application, a calendar application, an alarm application, a health care application (e.g., an application for measuring the amount of exercise or blood glucose), and an environmental information application (e.g., an application for providing atmospheric pressure information, humidity information, temperature information, and the like). Additionally or alternatively, the applications 134 may include an application associated with information exchange between the electronic device 101 and an external electronic device (e.g., the electronic device 104). The application associated with information exchange, for example, may include a notification relay application for transferring specific information to the external electronic device or a device management application for managing the external electronic device.

For example, the notification relay application may include a function of transferring notification information, generated in another application of the electronic device 101 (e.g., the SMS/MMS application, the e-mail application, the health care application, or the environmental information application), to an external electronic device (e.g., the electronic device 104). Additionally or alternatively, the notification relay application, for example, may receive notification information from an external electronic device (e.g., the electronic device 104) and provide the received notification information to a user. The device management application, for example, may manage (e.g., install, remove, or update) a function for at least a part of an external electronic device (e.g., the electronic device 104) communicating with the electronic device 101 (e.g., a function of turning on/off an external electronic device itself (or some components thereof) or adjusting the brightness (or resolution) of a display), an application running on the external electronic device, or a service provided in the external electronic device (e.g., a calling or messaging service).

According to various embodiments, the applications 134 may include an application specified according to an attribute (e.g., type) of an external electronic device (e.g., the electronic device 104). For example, when the external electronic device is an MP3 player, the applications 134 may include an application associated with music playback. Similarly, when the external electronic device is a mobile medical device, the applications 134 may include an application associated with health care. According to an embodiment, the applications 134 may include at least one of an application assigned to the electronic device 101 and an application received from an external electronic device (e.g., server 106 or the electronic device 104).

The applications 134 may also include an image processing program 135. The image processing program 135 may acquire a shared image generated from the image resource through the communication interface 160, determine an auxiliary image generated from a difference between display information of the electronic device 101 and the shared image, and generate a particular image based on the shared image and the auxiliary image. According to an embodiment, the image processing program 135 may read the auxiliary image from the image resource, or request for the auxiliary image to a content-providing server (e.g., the server 106) and receive the auxiliary image from the content-providing server (e.g., the server 106). According to an embodiment, the image processing program 135 may transmit the display information to the content-providing server and receive an auxiliary image corresponding to the display information. According to an embodiment, the image processing program 135 may transmit identification information on the shared image and the display information and receive auxiliary images corresponding to the display information and the identification information.

According to an embodiment, the image processing program 135 may process a low resolution image including at least a part of the image resource file to be the shared image. According to an embodiment, the image processing program 135 may process the remaining images except for the shared image as an auxiliary image in a particular resolution. According to an embodiment, the image processing program 135 may generate the shared image from at least one of an image resource file and a second image resource file of a resolution different from that of the image resource file. According to an embodiment, the image processing program 135 may acquire a second auxiliary image generated from a difference between the second image resource file and the shared image and generate a second particular image based on the shared image and the second auxiliary image.

The input/output interface 140, for example, may transfer instructions or data, input from a user through an input/output device (e.g., a sensor, a keyboard, or a touch screen, not shown), to the processor 120, the memory 130, and the communication interface 160 through the bus 110. For example, the input/output interface 140 may provide the processor 120 with data corresponding to a user's touch input through a touch screen (not shown). Further, the input/output interface 140 may, for example, receive instructions or data from the processor 120, the memory 130, and the communication interface 160 through the bus 110 and output the received instructions or data through the input/output device (e.g., a speaker or a display). For example, the input/output interface 140 may output voice data processed by the processor 120 to a user through a speaker.

The display 150 may display various pieces of information (e.g., multimedia data or text data) to a user.

The communication interface 160 may establish communication between the electronic device 101 and an external electronic device (e.g., the electronic device 104 or the server 106). For example, the communication interface 160 may be connected to the network 162 through wireless or wired communication and thereby communicate with the external device. The wireless communication, for example, may include at least one of wireless fidelity (WiFi), Bluetooth (BT), near field communication (NFC), a global positioning system (GPS), and cellular communication (e.g., LTE, LTE-A, CDMA, CDMA, UMTS, WiBro, or GSM).

According to an embodiment, the charger IC may include a charger IC for at least one of the wired charging and the wireless charging. Examples of the wireless charging include magnetic resonance charging, magnetic induction charging, and electromagnetic charging, and an additional circuit such as a coil loop, a resonance circuit, and a rectifier may be added for the wireless charging.

A battery gauge (not shown), for example, may measure the residual capacity, charge in voltage, current, or temperature of the battery 296. The battery 296 may store or generate electricity, and may supply power to the electronic device 200 by using the stored or generated electricity. The battery 296, for example, may include a rechargeable battery or a solar battery.

Each of the above described elements of the electronic device 200 according to the present disclosure may be formed by one or more components, and the names of the corresponding elements may vary according to the type of the electronic device 200. The electronic device 200 according to the present disclosure may include at least one of the above described elements, and may exclude some of the elements or further include other additional elements. Further, some of the elements of the electronic device 200 according to the present disclosure may be coupled to form a single entity while performing the same functions as those of the corresponding elements before the coupling.

An electronic device (e.g., the electronic device 200) may acquire various pieces of image data (or files) and use the acquired image data as images of various programs of the electronic device (e.g., the background image of the display 260, an icon displayed on the display 150 (of FIG. 1), and successive image resources to create an animation effect). An image provider (e.g., a content provider) may include various image resource files within an installation file (e.g., a theme installation file) and configure a server (e.g., the server 106 of FIG. 1) from which an electronic device (e.g., the electronic device 200) may download the installation file, and each server may include various installation files. The electronic device 200 may be configured to search for, download, and install such files, and read corresponding image resources and store the read image resources in a memory buffer for decoding or displaying them. This specification may describe a method for effectively supporting various resolutions in order to allow the electronic device 200 to use various image resources.

FIG. 3 illustrates an example of generating a shared image according to various embodiments.

Referring to FIG. 3, a content-providing server (e.g., the server 106) may generate a shared image 300 from an original image (or an image resource file). The shared image 300 may be generated from the image resource file and may be at least one of a low resolution image having a predetermined size, an image having a particular size, and a particular resolution image. The shared image 300 may be used for generating an image (e.g., a particular image) identical or similar to the original image through a method of synthesizing, modifying, copying, and merging one or more images (e.g., auxiliary images). When the shared image 300 and the particular resolution image (e.g., an image 301 or 303) are required, the content-providing server may generate an image (e.g., an auxiliary image) corresponding to a difference between the shared image 300 and the particular resolution image (e.g., the image 301 or 303). The auxiliary image may be generated by changing (or modifying) a resolution of a particular resolution image resource file (e.g., the image 301). For example, the auxiliary image may be a remaining image, which is left after the shared image 300 is separated from the image resource file (e.g., the image 301) (e.g., the auxiliary image may be described as a difference 311 between the shared image 300 and the particular resolution image 301).

According to an embodiment, the shared image 300 may be an image of a color component and/or a brightness component of the original image (image resource file) or an image of a resolution and/or a size of the original image. According to an embodiment, the auxiliary image may be a low brightness or achromatic image. Hereinafter, although it is described that the electronic device 101 generates a particular image identical or similar to an image resource file by using a shared image and an auxiliary image generated from the image resource file, more precisely, the electronic device 101 may generate a particular image configured to be identical or similar to the image resource file.

FIG. 4 illustrates an example of generating a shared image or an auxiliary image according to various embodiments.

Referring to FIG. 4, a content-providing server (e.g., the server 106 of FIG. 1) may generate a shared image by using a particular resolution image. According to an embodiment, when generating the shared image, the content-providing server may perform an operation for changing (or modifying) the resolution. The operation for changing the resolution may use a downsizing scheme to change a resolution at a predetermined level of the particular resolution image to a lower resolution. The content-providing server may select at least some pixels (or pixel values) in a particular resolution image 400. The content-providing server may generate a split image 410 including at least some pixels selected in the particular resolution image 400. The content-providing server may re-arrange pixels of the generated split image 410. When re-arranging the pixels of the split image 410, the content-providing server may re-arrange the pixels selected in the particular resolution image 400 to generate a predetermined resolution image (e.g., the shared image 300). Further, when re-arranging the selected pixels to generate the predetermined resolution image, the content-providing server may delete at least some of the pixels selected in the particular resolution image 400 or at least some of the remaining pixels, which do not include the selected pixels, and generate predetermined pixels. The content-providing server may reduce the image resolution and generate the shared image 300, which has a predetermined size, by re-arranging the pixels of the generated split image 410.

The content-providing server may generate the split image 410 by selecting predetermined pixels in the particular image corresponding to an original image (e.g., the original image 400). According to an embodiment, the content-providing server may select pixels that have a predetermined color or brightness larger than or equal to a predetermined value in the original image 400 based on configuration information (display information of the electronic device 101 (of FIG. 1), for example, the resolution). Further, the content-providing server may select pixels that have pixel values (e.g., outline or boundary) corresponding to predetermined brightness or saturation (e.g., predetermined brightness and color) in the original image 400 through a comparison with neighboring pixels. The content-providing server may generate the split image 410 using the selected pixels. The electronic device 101 may generate the shared image 300 (of FIG. 3) by arranging at least some of the pixels included in the split image 410 in a predetermined scheme. When generating the shared image 300 based on the original image 400, the content-providing server may generate the shared image 300 corresponding to an entire area of the original image 400 or generate the shared image 300 corresponding to a partial area of the original image 400.

The electronic device 101 (of FIG. 1) may generate the particular resolution image 400 (e.g., the original image 400) by synthesizing the shared image 300 and at least one image. When generating the particular resolution image 400 based on the shared image 300, the electronic device 101 may require an image (e.g., an auxiliary image 420) including at least a part of the particular resolution image 400.

The auxiliary image 420 may be acquired through an operation for generating the shared image 300 based on the original image 400. According to an embodiment, when generating the auxiliary image 420, the content-providing server (e.g., the server 106 of FIG. 1) may generate an image including the remaining pixels of the original image 400 except for the pixels included in the split image 410 as the auxiliary image 420. The content-providing server may insert at least one piece of information related to the generation of the shared image 300, identification information of the shared image 300, identification information of the auxiliary image 420, and identification information of the original image 400 into at least one of the original image 400, the shared image 300, and the auxiliary image 420.

When the information related to the shared image is included in the image data, the content-providing server may insert the information related to the shared image into a header of the image data or into separate data. When inserting the information on the shared image 300, the content-providing server may insert information on an arrangement pattern and the positions of the pixels included in the split image in the resolution before the split image 410 is re-arranged. The information on the arrangement pattern of the pixels included in the split image 410 and the pixel positions may be determined based on the original image 400. According to an embodiment of the size of the image data, the size of the shared data 300 may be smaller than the size of the image resource file 400, and the size of the auxiliary image 420 may be smaller than the size of the shared image 300. Further, the size of the image generated by synthesizing the shared image 300 and the auxiliary image 420 may be identical or similar to the size of the image resource file 400. According to various embodiments, the electronic device 101 may receive a request for transmitting a first resolution image and a second resolution image based on the shared image included in another electronic device (e.g., the electronic device 102 of FIG. 1). The electronic device 101 (of FIG. 1) may transmit the first resolution image and the second resolution image, and may transmit a first auxiliary image generated between the first resolution image and the shared image and a second auxiliary image generated between the second resolution image and the shared image. The electronic device 101 may further reduce the data size used for data transmission/reception when corresponding auxiliary data is transmitted rather than transmitting a particular resolution image that was requested to be transmitted.

An operation for generating the shared image or the auxiliary image by using the particular resolution image (e.g., the original image) is not limited to the operation of the electronic device 101, but may be described as the operation of the server 106 for providing the shared image 300 or the auxiliary image 420.

FIG. 5 is a flowchart illustrating an operation for generating a shared image or an auxiliary image based on an original image according to various embodiments.

Referring to FIG. 5, in operation 501, the electronic device 101 (of FIG. 1) may generate a shared image based on an image resource file. According to an embodiment, the electronic device 101 may select at least one pixel from pixels included in the image resource file, and generate a new image (e.g., a split image) including pixel values of the selected pixels. The electronic device 101 may generate a shared image of a predetermined resolution by re-arranging the pixels, which are selected from the image resource file and included in the split image. With respect to the pixels, which are selected from the image resource file and included in the split image, information on positions or arrangement of the pixels may be stored in the shared image. When an image having a particular resolution identical or similar to that of the image resource file is generated based on the shared image, the stored image may be used as information for determining positions of the pixels included in the shared image in the generated image.

In operation 503, the electronic device 101 may generate an auxiliary image based on the shared image. The electronic device 101 may generate a particular image (e.g., the original image) by synthesizing the shared image and the auxiliary image. The electronic device 101 may generate the remaining images of the image resource file except for the shared image as the auxiliary image. For example, the electronic device 101 may generate a shared image (e.g., a split image) having a resolution identical or similar to that of the image resource file in the operation for generating the image resource file. The split image may be an image for at least some pixels in the image resource file. The electronic device 101 may determine an image of the remaining areas of the image resource file except for the split image (e.g., an image including the remaining pixels of the pixels of the image resource file except for the pixels of the split image) as the auxiliary image. In operation 505, the electronic device 101 may provide the generated shared image and/or auxiliary image. According to an embodiment, the electronic device 101 may provide the shared image to handle a request for various resolution images. For example, when the electronic device 101 receives a request for transmitting an image of a particular resolution for the shared image from another electronic device (e.g., the electronic device 102), which provides the shared image, the electronic device 101 may transmit auxiliary data generated between the image of the particular resolution and the shared image.

The electronic device 101 (of FIG. 1) may generate one shared image corresponding to the same image of various resolutions. The electronic device 101 may generate at least one auxiliary image with respect to shared data and an image of a particular resolution.

In operation 601, the electronic device 101 may generate a common shared image in a plurality of images of different particular resolutions. According to an embodiment, the electronic device 101 may generate a shared image including a common pixel between an image of a first particular resolution (e.g., a first original image) and an image of a second particular resolution (e.g., a second original image). The shared image may be a low resolution image, which is downsized from the first original image and the second original image.

In operation 603, the electronic device 101 may generate a first auxiliary image based on the first original image and the shared image. According to an embodiment, the electronic device 101 may generate a shared image of a common resolution by using two or more different particular resolution images (e.g., the image 301 or 303 of FIG. 3). According to an embodiment, the electronic device 101 may generate one shared image 300 based on two or more image source files of different resolutions and generate an auxiliary image corresponding to a difference between each of the image resource files and the shared image 300. For example, the electronic device 101 may generate the remaining images of the first original image except for the shared image as the first auxiliary image. For example, the electronic device 101 may configure an image including the remaining pixels except for pixels corresponding to the pixels included in the shared image among the pixels included in the first original image as the first auxiliary image.

In operation 605, the electronic device 101 may generate a second auxiliary image based on the second original image and the shared image. According to an embodiment, the electronic device 101 may generate the remaining images of the second original image except for the shared image as the second auxiliary image. For example, the electronic device 101 may configure an image including the remaining pixels except for pixels corresponding to the pixels included in the shared image among the pixels included in the second original image as the second auxiliary image. When performing operations 603 and 605 described above, the electronic device 101 may sequentially perform the operations according to a preset priority or may simultaneously perform the operations.

The electronic device 101 may end the embodiment of FIG. 6 after performing operation 605.

The electronic device 101 may transmit the generated shared data to another electronic device (e.g., the electronic device 102) and receive a request for transmitting the first original image or the second original image from the electronic device 102. The electronic device 101 may transmit an auxiliary image (e.g., the first auxiliary image) corresponding to the requested image of the particular resolution (e.g., the first original image). The electronic device 102 having received the auxiliary image may generate the image of the particular resolution (e.g., the first original image), which was requested to be transmitted from the electronic device 101 based on the shared image and the received auxiliary image (e.g., the first auxiliary image).

FIG. 7 is a flowchart illustrating an operation for generating a shared image or a plurality of auxiliary images by an electronic device according to various embodiments.

The electronic device 101 (of FIG. 1) may generate a common shared image based on different particular resolution images and generate an auxiliary image corresponding to the shared image and each of the particular resolutions.

In operation 701, the electronic device 101 may generate the shared image based on an image of a first particular resolution (e.g., a first original image). According to an embodiment, the electronic device 101 may select at least one pixel from pixels included in the first original image, and generate a new image (e.g., a split image) including pixel values of the selected pixels. The electronic device 101 may generate a shared image of a predetermined resolution by re-arranging the pixels, which are selected from the first particular resolution and included in the split image. Information on positions of the pixels, which are selected from the first particular resolution and included in the split image, in the first particular resolution or information on arrangement of the pixels may be stored in the shared image. When an image having a particular resolution identical or similar to the first particular resolution is generated based on the shared image, the stored image may be used as information for determining positions of the pixels included in the shared image in the generated image.

In operation 703, the electronic device 101 may generate a first auxiliary image based on the first original image. When generating the first original image by using the shared image, the electronic device 101 may synthesize the first original image by using at least one first auxiliary image. According to an embodiment of generating the first auxiliary image, the electronic device 101 may generate the remaining images of the first original image except for the shared image as the first auxiliary image. For example, the electronic device 101 may generate a shared image (e.g., a split image) of a resolution identical or similar to that of the first original image in the operation for generating the first original image. The split image may be an image for at least some pixels in the first original image. The electronic device 101 may determine an image of the remaining areas of the first original image except for the split image (e.g., an image including the remaining pixels except for the pixels of the split image in the pixels of the first original image) as the first auxiliary image. The electronic device 101 may synthesize the first original image based on the shared image and the first auxiliary image.

In operation 705, the electronic device 101 may generate an image of a second particular resolution (e.g., a second original image) based on the first original image. According to an embodiment, the electronic device 101 may acquire the second original image by performing a downsizing operation, which deteriorates the resolution and/or quality of the first original image. The electronic device 101 may determine pixels included in the first original image, which correspond to the pixels included in the shared image, and generate second original data in a state where the determined pixels are not excluded.

In operation 707, the electronic device 101 may generate a second auxiliary image based on the second original image. When generating the second original image by using the shared image, the electronic device 101 may synthesize the second original image by using at least one second auxiliary image. According to an embodiment of generating the second auxiliary image, the electronic device 101 may generate the remaining images of the second original image except for the shared image as the second auxiliary image. For example, the electronic device 101 may generate a shared image (e.g., a split image) of a resolution identical or similar to that of the second original image in the operation for generating the second original image. The split image may be an image for at least some pixels in the second original image. The electronic device 101 may determine an image of the remaining areas of the second original image except for the split image (e.g., an image including the remaining pixels except for the pixels of the split image in the pixels of the second original image) as the second auxiliary image. The electronic device 101 may synthesize the second original image based on the shared image and the second auxiliary image.

The electronic device 101 may end the embodiment of FIG. 7 after performing operation 707.

FIG. 8 illustrates the generation of a particular image in an electronic device according to various embodiments.

Referring to FIG. 8, the electronic device 101 (of FIG. 1) may generate an image 830 of a particular resolution based on the shared image 300 (of FIG. 3) and an auxiliary image 820. According to an embodiment, when an image of a high resolution (e.g., an image of a particular resolution) identical to that of the shared image is required, the electronic device 101 may determine an auxiliary image of a resolution identical or similar to that of the shared image and the particular resolution. The electronic device 101 may enlarge the shared image. For example, the electronic device 101 may enlarge the resolution of the shared image to an image of a particular resolution (e.g., a resolution enlarged image 810).

The electronic device 101 may arrange pixels included in the shared image in the resolution enlarged image 810 at the position corresponding to the image of the particular resolution based on configuration information. The electronic device 101 may generate a high resolution image of the requested particular resolution based on the resolution enlarged image and the auxiliary image 820. The electronic device 101 may generate an image 830 of a particular resolution through a copying, merging, modifying, or synthesizing scheme based on the resolution enlarged image 810 and the auxiliary image 820. The image 830 of the particular resolution generated by the electronic device 101 may be an image of quality identical or similar to that of the original image of the particular resolution requested based on the shared image.

FIG. 9 is a flowchart illustrating a process of generating a particular image in an electronic device according to various embodiments.

Referring to FIG. 9, in operation 901, the processor 120 (of FIG. 1) may receive an image resource file from the content-providing server through the communication interface 160 (of FIG. 1). The image resource file may be an image file, which can be applied to a background image of the electronic device 101 (of FIG. 1), a home screen image, a lock screen, and an icon of the home screen image or an image installation file including a plurality of successive images for an animation effect. The image resource file may include only a shared image or include both the shared image and an auxiliary image. The image resource file may refer to the above described original image.

In operation 903, the processor 120 may read the shared image from the image resource file. The reading of the shared image may refer to extracting or reading the shared image from the image resource file.

In operation 905, the processor 120 may identify display information of the electronic device 101. The display information of the electronic device 101 may be a resolution or a pixel value of the display 150 (of FIG. 1). Alternatively, the display information may be a resolution or a pixel value set to the electronic device 101 by the user.

In operation 907, the processor 120 may determine an auxiliary image by using a difference between the shared image and the display information. The auxiliary image may be read by the processor 120 from the image resource file based on the difference between the shared image and the display information. Alternatively, the processor 120 may receive the auxiliary image from the content-providing server. To this end, the processor 120 may transmit identification information of the shared image and the display information to the content-providing server. The content-providing server may search for the auxiliary image corresponding to the identification information of the shared image and the display information and transmit the found auxiliary image to the electronic device 101.

In operation 909, the processor 120 may generate a particular image based on the shared image and the auxiliary image. The particular image may refer to an image made to be suitable for the display information of the electronic device 101. For example, the processor 120 may generate the particular image according to the resolution of the display 150.

When the particular image is generated, the display 150 may display the particular image. For example, when the image resource file is received to be set as a background image of the electronic device 101, the display 150 may display the particular image as the background image.

FIGS. 10A and 10B are flowcharts illustrating an operation for acquiring an auxiliary image in an electronic device according to various embodiments.

FIG. 10A is a flowchart illustrating an operation for generating a particular image in an electronic device according to various embodiments.

Referring to FIG. 10A, in operation 1001, the electronic device 101 (of FIG. 1) may determine the display information of the electronic device 101. According to an embodiment, when the electronic device 101 sets the background image of the display 150 (of FIG. 1) of the electronic device 101 based on the shared image, the electronic device 101 may determine the resolution of the display 150. When the electronic device 101 determines an icon image of a particular program based on the shared image, the electronic device 101 may determine the resolution of the icon.

In operation 1003, the electronic device 101 may determine an auxiliary image of the shared image based on the determined display information. The electronic device 101 may include at least one auxiliary image of the shared image in the form of the same category or the same package. When determining the auxiliary image corresponding to a particular resolution based on the shared image, the electronic device 101 may use identification information of the shared image. According to an embodiment, when determining the particular resolution to be used based on the shared image, the electronic device 101 may identify the identification information of the shared image. The electronic device 101 may determine the auxiliary image corresponding to the particular resolution based on the identified identification information of the shared image. Alternatively, the electronic device 101 may determine the auxiliary image based on the display information of the display 150, the determined display information, or the identification information of the shared image.

In operation 1005, the electronic device 101 may generate the particular image based on the shared image and the auxiliary image. According to an embodiment, the electronic device 101 may enlarge the size of the shared image or increase the resolution of the shared image and merge the shared image with the auxiliary image, so as to generate the particular image.

The electronic device 101 may generate the particular image based on the enlarged shared image and the auxiliary image. When generating the particular image, the electronic device 101 may synthesize the shared image and the auxiliary image through a merging, modifying, or copying scheme.

The electronic device 101 may end the embodiment of FIG. 9 after performing operation 905.

FIG. 10B is a flowchart illustrating an operation for acquiring an auxiliary image in an electronic device according to various embodiments.

According to various embodiments, the embodiment of FIG. 10B corresponds to a flowchart illustrating an operation for acquiring an auxiliary image by making a request for transmitting an image of a particular resolution determined based on a shared image by the electronic device 101 or a request for transmitting an auxiliary image corresponding to the particular resolution to at least one other electronic device (e.g., the server 106) connected through network communication. Hereinafter, various embodiments of FIG. 10B may correspond to operations after operation 1001 of FIG. 10.

In operation 1010, the electronic device 101 may transmit the determined display information and the identification information of the shared image to the content-providing server (e.g., the server 106). Alternatively, the electronic device 101 may transmit the display information and the identification information of the shared image to another electronic device (e.g., the server 106) connected through network communication.

In operation 1020, the electronic device 101 may receive the auxiliary image from the content-providing server. According to an embodiment, the electronic device 101 may receive a particular image identical or similar to the shared image from the content-providing server, but may receive an auxiliary image that has a capacity smaller than that of the particular image or the shared image, thereby reducing the amount of transmitted/received data.

When operation 1020 is performed, the electronic device 101 may end the embodiment of FIG. 10B or may perform operation 1005 of FIG. 10A. The electronic device 101 may generate (or synthesize) the particular image based on the shared image and the received auxiliary image in operation 1005.

FIG. 11 illustrates an operation for acquiring a particular resolution image corresponding to a plurality of particular resolutions based on a shared image in an electronic device according to various embodiments.

According to various embodiments, the electronic device 101 (of FIG. 1) may generate images of various resolutions based on the shared image. According to an embodiment, the electronic device 101 may require an image (e.g., a content image) indicating contents of various functions such as a graphic interface displayed on the display 150 and/or an image of a resolution optimized for each content. When determining each content image, the electronic device 101 may acquire an image of a corresponding resolution, but may generate an image corresponding to each resolution based on the shared image and the auxiliary image corresponding to one provided resolution. When acquiring the shared image, the electronic device 101 may acquire a plurality of shared images used for various contents as data in package form. The electronic device 101 may generate an image of a particular resolution corresponding to a content to be used, based on the acquired shared data.

According to an embodiment, when the electronic device 101 uses the shared image as an image of an execution icon 1101 (e.g., a short cut icon) of a particular program displayed on the display 150 (of FIG. 1), the electronic device 101 may identify a resolution of the shared image and a first particular resolution of the icon 1101. When the resolution of the shared image and the first particular resolution of the icon 1101 are different from each other, the electronic device 101 may determine whether there is an image of the first particular resolution of the shared image corresponding to the first particular resolution of the icon 1101. The electronic device 101 may identify a first auxiliary image corresponding to the first particular resolution of the icon 1101 based on the identification information of the shared image. When the first auxiliary image is not identified in the memory 130 (of FIG. 1), the electronic device 101 may make a request to the server 106 (of FIG. 1) for transmission of the first auxiliary image and the image of the first particular resolution. When transmitting the image transmission request information to the server 106, the electronic device 101 may also transmit the identification information of the shared image and information on the first particular resolution of the icon 1101. The electronic device 101 may receive the first auxiliary image corresponding to the first particular resolution of the icon 1101 from the server 106. The electronic device 101 may generate the image of the first particular resolution corresponding to the resolution of the icon 1101 based on the shared image and the first auxiliary image. The electronic device 101 may set the generated image of the first particular resolution as the image of the icon 1101.

As described above, although shared images used for respective contents are distinguished from each other, this is only for describing various embodiments, and it is apparent that one shared image may be used for various contents. According to an embodiment, the electronic device 101 may use the shared image as an image of another content 1103 (e.g., a background image).
